NoSQL and SQL: key-value access always scale

By Franck Pachot

I have written about some NoSQL myths in previous posts ( and here) and I got some feedback from people mentioning that the test case was on relatively small data. This is true. In order to understand how it works, we need to explain and trace the execution, and that is easier on a small test case. Once the algorithm is understood it is easy to infer how it scales. Then, if readers want to test it on huge data, they can. This may require lot of cloud credits, and I usually don’t feel the need to do this test for a blog post, especially when I include all the code to reproduce it on a larger scale.

Ever wonder about Big Data and what exactly it means, especially if you are already an Oracle Database professional?

I was inspired to write this from the recent incident involving NSA scooping up Verizon call data invading privacy of the citizens.
